Description

코어-시스형 복합방사 섬유용 수지조성물{Core-sheath type resin composition for conjugate spinning fiber}Core-sheath type resin composition for conjugate spinning fiber

본 발명은 코어-시스형(core-sheath type) 복합방사 섬유용 수지조성물 및 이로부터 제조된 단섬유 부직포에 관한 것이다. 보다 상세하게는, 본 발명에 의한 코어-시스형 복합방사 섬유용 수지조성물에서 코어(core)는 폴리에틸렌테레프탈레이트로 구성되고 시스(sheath)는 (a) 고밀도 폴리에틸렌 및 (b) 상기 (a)를 사용하여 제조된 변성 폴리에틸렌으로 구성됨으로써, 우수한 방사성을 유지하면서 강도가 우수한 부직포를 제조할 수 있다. The present invention relates to a resin composition for core-sheath type composite spun fiber and a short fiber nonwoven fabric prepared therefrom. More specifically, in the resin composition for the core-sheath composite spun fiber according to the present invention, the core is composed of polyethylene terephthalate and the sheath is (a) high density polyethylene and (b) the (a) By using the modified polyethylene produced using, it is possible to produce a nonwoven fabric having excellent strength while maintaining excellent spinning properties.

폴리에틸렌(시스)/폴리에틸렌테레프탈레이트(코어) 복합방사 단섬유의 경우는 기존의 폴리에틸렌테레프탈레이트 섬유에 비해 낮은 부직포 성형온도, 부드러운 감촉 등으로 기저귀, 위생자재 등에 다양하게 사용되면서 기존 부직포 시장에서 적용 영역을 급속히 넓혀 가고 있다. 그러나, 상기 복합방사 단섬유는 폴리에틸렌과 폴리에틸렌테레프탈레이트 사이에 상용성이 없는 관계로 계면에서의 분리가 발생하고, 이로 인해 섬유의 강도가 떨어져 결과적으로 부직포 제조시 강도 저하 등의 성형 불량을 초래하는 경우가 발생한다.Polyethylene (cis) / polyethylene terephthalate (core) composite spun short fibers are used in diapers and sanitary materials due to their low nonwoven fabric forming temperature and soft touch, compared to conventional polyethylene terephthalate fibers, and thus are applicable to the existing nonwovens market. Is expanding rapidly. However, since the composite spun short fibers have no compatibility between polyethylene and polyethylene terephthalate, separation occurs at the interface, and as a result, the strength of the fibers is reduced, resulting in molding defects such as a decrease in strength when manufacturing nonwoven fabrics. The case occurs.

이에, 상기의 단점을 개선하기 위한 복합방사 단섬유 부직포용 폴리에틸렌 수지에 대한 연구가 진행되었다. 구체적으로, 미국특허출원 제 5,372,885호에는 열가소성 복합섬유로서 코어는 폴리에틸렌테레프탈레이트 또는 폴리부틸렌 테레프탈레이트를 사용하고, 시스는 무수화합물을 0.1~1wt%를 갖는 변성 폴리에틸렌 수지를 2~15wt%를 첨가한 폴리올레핀계 수지를 사용하여 염색성이 우수한 복합방사 섬유를 제조하는 방법이 기재되어 있다. 그러나, 상기 방법은 염색성을 높이기 위해 첨가되는 변성 폴리에틸렌 수지의 함량이 높을 경우, 변성 폴리에틸렌 수지 제조시 생성되는 겔 성분으로 인해 방사성이 떨어지는 문제점이 있다. 또 다른 예로, 미국특허출원 제 5,948,529호에는 열가소성 복합섬유로서 코어는 폴리에틸렌테레프탈레이트와 극성기를 갖는 에틸렌 공중합체의 배합으로 이뤄지고, 시스는 폴리에틸렌 수지를 사용하여 높은 계면접착력을 갖는 복합방사 섬유가 기재되어 있다. 그러나, 상기 섬유는 코어성분의 흐름성 차이로 인해 방사성이 떨어지는 단점이 있다. Thus, the study on the polyethylene resin for composite spun short fiber nonwoven fabric to improve the above disadvantages. Specifically, US Patent Application No. 5,372,885 uses a polyethylene terephthalate or a polybutylene terephthalate as a thermoplastic composite fiber, and the sheath adds 2 to 15 wt% of a modified polyethylene resin having 0.1 to 1 wt% of anhydrous compound. A method for producing a composite spun fiber having excellent dyeability using a polyolefin resin is described. However, when the content of the modified polyethylene resin is added to increase the dyeability, the method has a problem of poor radioactivity due to the gel component produced during the production of the modified polyethylene resin. As another example, U.S. Patent Application No. 5,948,529 describes a thermoplastic composite fiber in which the core is composed of polyethylene terephthalate and an ethylene copolymer having a polar group, and the sheath is a composite spinning fiber having a high interfacial adhesion force using a polyethylene resin. have. However, the fiber has a disadvantage in that the spinning is poor due to the flowability of the core component.

이에, 본 발명자들은 우수한 방사성을 유지하면서 폴리에틸렌과 폴리에틸렌테레프탈레이트 수지의 상용성 문제를 해결하여 강도가 개선되는 복합방사 섬유용 수지조성물에 대해 연구하였다. 그 결과, 코어-시스형 복합방사 섬유용 수지조성물에 있어서 시스성분을 고밀도 폴리에틸렌과 이를 사용하여 제조된 변성 폴리에틸렌으로 구성함으로써 우수한 방사성을 유지하면서 폴리에틸렌과 폴리에틸렌테레프탈레이트 사이의 상용성 문제를 해결하여 강도가 우수한 부직포를 제조할 수 있음을 확인하고 본 발명을 완성하였다. Thus, the present inventors have studied a resin composition for composite spun fiber to improve the strength by solving the compatibility problem of polyethylene and polyethylene terephthalate resin while maintaining excellent radioactivity. As a result, in the resin composition for the core-sheath type composite spun fiber, the sheath component is composed of high density polyethylene and modified polyethylene produced using the same, thereby solving the problem of compatibility between polyethylene and polyethylene terephthalate while maintaining excellent radioactivity. It was confirmed that the excellent nonwoven fabric can be completed the present invention.

따라서, 본 발명의 목적은 우수한 방사성을 유지하면서 강도가 우수한 부직포를 제조할 수 있는 코어-시스형 복합방사 섬유용 수지조성물을 제공하는 것이다.
